Regarding this question, we start to analyze from many aspects, whether the best plant growth light depends on your current needs (the following answer comes from the authoritative blog bbier):
The main reason for using the best led grow lights is that they can reduce or eliminate dependence on natural light (sunlight). Light is essential for plant growth, but it is often in short supply (for example, indoors, in winter or in densely populated urban areas). Best led grow lights enable us to grow plants in different places or at some time of the year that might otherwise not be possible. The best led grow lights can be used for seed initiation, indoor plants, herbs, flowers, fruits, vegetables and so on.
Best led grow lights are used in horticulture, indoor horticulture, plant propagation and food production, including indoor hydroponics and aquatic plants. Although most plant growth lamps are used for industrial purposes, they can also be used in families.
Sunlight is a unique asset that can never really be replaced — even the best grow light in the world. However, sunlight has many uses — it keeps us warm, it lets you see the light pole so you don’t walk into it, it powers the photosynthesis of plants. Some of the conveniences that sunlight provides are important to plants, but not all of them. In fact, plant growth lights can provide many convenience facilities for plant care.
Best led grow lights vary widely in the amount of radiation (PAR) available to their plants. At the same time, plants vary greatly in the amount of light they need. However, when it comes to growth lights, you need to consider two main variables, and they can usually be adjusted — they are distance and duration.
Grow Light Quality
One of the major differences between best led grow lights and the ordinary bulbs you use to illuminate homes is the spectrum they distribute. The human eye can “see” light in the frequency range of about 380 (we call it “purple”) to 740 (red “) nanometers, but we are most sensitive to yellow light, so it is the cheapest and easiest way for us to light our home, that is to provide yellow light for us. Although plants can and do appreciate light from the visible spectrum (or even beyond), the most important frequencies for them are red and blue. That’s why you find a lot of plant lights that look purple on the Internet — a combination of red and blue. Personally, we do not love these purple plant growth lights. Of course, from an energy point of view, they are efficient, but they also ignore other frequencies, such as ultraviolet, infrared.
Three-by-three feet of plant coverage, 2.5 x 2.5 feet of flowering coverage, 50,000-hour lifespan; customizable lighting with color change and dimming, including thermometer, hygrometer and timer; Samsung + Osram. This grow light comes with a thermometer and timer that allows you to determine how long the light has been on and how warm your grow space is. Its exterior light controls also let you dim its full-spectrum lighting as needed.
SAMSUNG LM301H diode and OSRAM 660NM diode — OSRAM is one of the two largest light source manufacturers in the world. Provides a beneficial and reliable option for your plants. Other brands distribute too much light to the center and too little light to the outer edges. The larger size of the KS5000 ensures enough light for every plant from corner to center. The excellent available PPE-KS5000 enables indoor farms to reduce energy usage. Limit the temperature inside the tent as the distance between the plug and the light is 13.12 feet (400 cm). Consists of 3000K warm white, 5000K neutral white and 660nm deep red. Recommended for: commercial growth, greenhouses, home growing, soil, hydroponics, aeroponics or hydroponic systems, indoor farming or gardening.
This is a mid-range LED quantum board from the Horticultural Lighting Group product line. The light has 2 boards each containing 288 (576 total) Samsung LM301B diodes. The quantum board is placed on a larger aluminum plate with a dimmable Meanwell driver on the other side. The HLG 300 V2 measures 18" x 20" x 3". It comes with a 120v plug, so if your country uses 240v, you will need a 120V to 240V adapter.
The HLG550 V2 Indoor Gardening LED Light is designed to replace single ended 1000W HID lights. Each lamp uses our custom-designed 4 high-efficiency white light quantum boards made by Samsung. 500W, 1152 maximum output Samsung LM301B LEDs. Available in 3000K (flowering and full cycle) or 4000K (Veg only) spectrum. For optimal canopy penetration and easy viewing, ideal for seedling harvest growth. Recommended for: Grow tents, grow rooms, large indoor growing, vegetative growth and/or flowering, full cycle growth from seedling to flowering.
